The measurement used by the Ghost Prison Race is quite similar to the kilometer used by the Human Race.
In this era of the Star River, a distance of one billion kilometers is not considered much.
However, in the Netherworld Realm, the situation is completely different.
Without the Sea of Source Power as a medium, Spiritual Power cannot roam in all directions. Without roaming Spiritual Power, it's impossible to lock onto a distant location for a Space Jump.
The Marvels owned by Gao Xuan cannot be used; the simplest method is to ride the Celestial Dragon Eye to fly there. The time this would take is hard to predict.
On the other hand, Gao Xuan couldn't help but feel amazed by the vastness of the Wuman Realm.
The distance to Chujiang City is one billion kilometers, which means that within this distance as a radius, the area is a stable material world.
It's important to note that the largest solid planets do not exceed a diameter of ten thousand kilometers.
